摘要
基于割草机器人系统EMC设计的技术总结,分析边界线负载端子骚扰电压形成机理和特点,采取将边界信号由方波调整为梯形脉冲,串联电阻均衡边界线阻抗并加强电源端和边界线负载电路滤波的方法抑制传导辐射。经检测,各项指标达到欧盟相关EMC标准要求。
Based on the surnlnary of EMC design technology of robotic lawnmowers system, analyzes the formation mechanism and characteristics of the disturbance voltage of the load terminals on the boundary line. Then the boundary signal is adjusted to trapezoidal pulse instead of square wave, series resistance balances boundary wire impedance, and filter is strengthened for the power supply port and the boundary wire load circuit. Professional testing results show that, the EMC technical target of the robotic lawnmower has reached the EU standards.
